Using the Transceiver as a Megaphone (Public Address)
Public Address (PA) enables the transceiver to be used in place of a megaphone. This function is used for a bus
announcement, etc.
This section describes behaviors unique to a Multi RF Deck/ Multi Control Head structure.
Public Address
can be toggled between enabled and disabled by any of the following key operations:
1. Pressing the
Public Address
key toggles
Public Address
between enabled and disabled.
2. Entering Menu Mode by pressing the
Menu
key, and then executing “Public Address” can toggle
Public Address
between enabled and disabled.
Public Address
functions by using the external speaker (KES-3 or KES-5) connected to RF Deck 1. Therefore, the behavior
of RF Deck 1 is restricted as follows:
0
While
Public Address
is enabled and the
PTT
switch is pressed, RF Deck 1 does not perform the reception behavior.
The other RF Decks perform the reception behavior regardless of the status of the
PTT
switch.
0
The operation to toggle
Public Address
between enabled and disabled is available only if the Selected RF Deck is RF
Deck 1. When the Selected RF Deck is RF Deck 2 or RF Deck 3, the operation to toggle
Public Address
between enabled
and disabled is unavailable.
If the External PTT (PA) is entered from the AUX Input port of RF Deck 2 or RF Deck 3, the audio is emitted from the external
speaker of the RF Deck from which the External PTT (PA) is entered.
